Patent CA-2504133-C (CA)
Inventor: LEWIS GARY
IPC: F01N3/20
Filed: 2003-10-28
Granted: 2012-01-03
Abstract: A fertilizer system is provided using extraction of nitrogen compounds and other plant nutrients from combustion exhaust gases, and which is particularly suited for use with an agricultural irrigation system or engine driven plant care equipment including self-propelled tractors, mowers and the like. The system includes an exhaust chamber in communication with the motor driving a pump of the system for receiving the exhaust gases therethrough. Water is injected into the exhaust chamber for mixing with the exhaust so that the steam being formed absorbs various nitrogen compounds and other plant nutrients from the surrounding hot exhaust gases. The steam is subsequently condensed in a condensing chamber from which condensate is collected and dispensed into the inlet of the pump with water circulated therethrough. The water is thus enriched with various nitrogen compounds and other plant nutrients absorbed from the exhaust gases before being dispensed to a planted area by an irrigation system or a sprayer attachment on a self-propelled tractor, mower and the like.

Title: Device authentication
Inventor: BROWN MICHAEL K
IPC: H04Q7/36
Filed: 2005-04-27
Granted: 2010-11-02
Abstract: Authentication of two devices in communication with a third device is achieved where the first and second devices each possess a shared secret value. The authentication includes communication of authentication values from the first device to the second device using the third device. Similarly, there is communication of values from the second device to the first device using the third device. The third device retains the communicated values. The values are calculated to permit the third device to authenticate the first and second devices without the third device receiving the shared secret value. The authentication may be used to establish a communications channel between the first and the second devices.

Title: High efficiency thermal ink jet printhead
Inventor: NORTH ANGUS JOHN
IPC: B41J2/05
Filed: 2003-11-17
Granted: 2009-11-03
Abstract: There is disclosed an ink jet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle (3).  Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble (12) therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is configured such that an actuation energy of less than 500 nanojoules (nJ) is required to be applied to that element to heat it sufficiently to form such a bubble (12) in the bubble forming liquid (which liquid can also be the ink). This configuration thus provides for a high efficiency printhead.

Abstract: A system and method of creating and communicating with wireless component applications is provided. Mobile communication devices communicate with a web service via a wireless network, the Internet, and optionally a message-map service. Each wireless component application is executed by a component framework on one of the mobile communication devices, and comprises data components, presentation components, message components, and workflow components. The component framework executes the component application in an application container which provides access to framework services which include a communication service, a screen service, a persistence service, an access service, a provisioning service, and a utility service. Messages can be sent from the component application to the message-map service, which converts each of the messages to a format required by the web service using an application message-map, and then sends the message to the web service. The web service sends a response to the message-map service, which converts the response to the format required by the wireless component application, and sends the response to the wireless component application.

Filed: 2005-02-04
Granted: 2013-11-12
Abstract: A stud or joist sensor device and associated sensing method using a ratio of capacitance measurements from a plurality of capacitive sensing elements. The device locates a feature of an object or discontinuity behind a surface or wall, such as an edge and/or a center of a stud behind the surface, a joist under a floorboard, a gap behind sheetrock, a metal conductor behind a surface or the like. The device may be moved over a surface, thereby detecting changes in capacitance. The change in capacitance is due to the effective dielectric constant caused by the passage over an object such as a stud. When two capacitive sensing elements provide equivalent capacitance measures, the device is over a centerline of a stud. When a ratio of the capacitance measurements equals a transition ratio, the device is over an edge of the stud.

A Reed-Solomon (RS) encoder RS-codes the randomized data packets by adding first parity data, and a data interleaver interleaves the RS-coded data packets. A trellis encoder trellis-encodes the interleaved data packets, wherein the trellis encoder may be initialized when a known data sequence is inputted thereto.

IPC: A61F9/01
Filed: 2005-06-27
Granted: 2010-04-20
Abstract: A system for performing a corneal transplantation includes a laser source for generating a laser beam and a chair for positioning a patient relative to the laser source. A stabilizing element, engageable with the laser source, is fixated on the anterior surface of the patient's cornea to hold the cornea in alignment with the laser source. The laser source is then used to remove diseased tissue from the cornea of the patient, thereby creating a corneal cavity of known dimensions. In a subsequent step, a donor graft that was previously photoaltered to have substantially the same dimensions as the corneal cavity, is transplanted into the corneal cavity.
